The figure, not drawn to scale, is made up of 2 identical squares, STUV and WXYZ. The length of each square is 27 cm. Point W is the centre of square STUV.
- What fraction of the figure is unshaded?
- What is the area of the shaded part?
(a)
If we pivot the square WXYZ from point W, we can see that the shaded area is
14 of square WXYZ.
Fraction of the figure that is shaded =
17 Fraction of the figure that is unshaded
= 1 -
17=
67 (b)
Area of each square
= 27 x 27
= 729 cm
2 Area of the shaded part
=
14 x 729
= 182.25 cm
2 Answer(s): (a)
67; (b) 182.25 cm
